APPARATUS FOR HANDLING MATERIAL IN CENTRIFUGAL MACHINES.

-Application filed June 13, 1912.

.chinesf and I do hereby declare the following to he a full. clear. and exact description of the same. reference being had to the accompanying drawings. forming a part of this specification. and to the referenceaiumerals' marked thereon.

The present invention relates to the treatment of relatively light materials and articles of small weight. having reference particularly to machines of the type in which material is supported against a rotating basket by the rapid movement of the latter, and is there subjected to the particular action for which the machine is intended.

The invention contemplates a novel proc ess and apparatus for handling such mate rials. and it has for its object to provide a machine from which .the material is automatically discharged. therelrv enabling large volumes to he handled expeditiously. and increasing the capacity and elliciency of the machine by obviating the necessity of unloading by hand.

The invention further consists in a novel construction and arrangement of parts which enables the'machine to be readily ::'harged. and automatically operating instrumentalities for effecting the treating and discharging of the material at successive predetermincal intervals.

To these and other ends the invention consists in certain improvements and combinations of parts. all as will be hereinafter more fully described. the novel features being pointed out in the claims at the end of the specification. I

In the drawings: Figure l is a view in side elevation of a machine constructed in accordance with a preferred embodiment of the invention: Fig. 2 1s a transverse sectional view of Fig. .1, with parts omitted;

Similar reference numerals throughoutthe several figures indicate the same parts.

The invention may be variously applied in drying, coating or otherwise treating different materials and relatively light articles, and in the present application, I disclose a preferred form of apparatus. primarily designed for treating corks, or cork disks for bottle shippers or caps although it may be employml in the treatment of other materials as well.

In the machine of the present embodt s0 ment. mechanism is provided for successively applying solutions of paraflin and glycerin to corks, or cork disks, the corks being supported against a rotating annular basket having an unobstructed Open bottom, and which serves to extract the surplus liquid. leaving the corks free to fall into a suitable discharge when the movement of the basket ceases. In general, the machine includes two sections, one for treating with one material. as parattin. and the other for subsequentlytreating with another material. as glycerin. provision being made for feeding the articles to the first section, discharging and feeding them to the second section. and thereafter discharging them from the latter when the operation is completed. Each section includes a plurality of bas kets, which may be constructed in any suita able way to' afl'ord an unobstructed open bottom, each of the baskets being mounted to rotate, and to revolve about an axis com mon to all. The baskets of each section are mounted on a rotary support, means being provided for rotating the supports. while each support carries a plurality of motors. corresponding to the number of baskets each basket being preferably mounted on its motor shaft. The supports are Illtfllllllb tently rotated to bring the several baskets mentioned, as shown in Fig. 3.

to the feeding and discharging points suecessively, Iwhileeaeh basket is stopped at;

n-edetermined intervals to permit the dis rharge of the material after it is-treated. The unite-rial may-be fed to the baskets in any-eonvenie t manner. this being preferably aeeomph. led in the ease of material such as eork disks for bottle stoppershy means of suitable blowers, whiehplaee the. materiallin".eontaet with the vertical walls of the baskets, while th'edatter are rotating, and the diseharge of the "material is elferted by stopping the" movement of the haskets, and permitting the material to fall therefrom. 3

Referring more partieularly to the drawings, and H designate the twoseetions of the machine, said seetions ineluding the supports 11.,and ll. resptatively,.on whieh are.

mounte gl the baskets or containers arranged 'wlthm the casings 11,", a, 1L and 11", II, II,

respectively, The several baskets are simil arly arranged, and for eon.venien e,d will "deserlbe one of these, as shown \nFig. i,-

the basket being designated at 16". and disposed w thin the easing 11. The casing 10 is suitably attached to and carried by aspider 11.- w hirh is mounted on the support a. The basket'uf' is preferably inverted, as Sh n, or otherwise constructed to-atford an unobstructed open bottom through which tlie material is dlseharged, and is pro- .vided with a tlarin mouth'uand a to) portionu. .The basket is mounted on the shaft 11..-', \\'hieh preferably is part of the moimshaft, the basket driving. motorsgheing designated-at A", A and it", I, and .B".

The basket 16'' preferably consists of -a-- hollow perforate metal cylinder against the side of whieh the material is supported. 'here the material is to be treated with paraffin, or a similar substanre, it is desirable to heat the basket in order. to maintain the treating sllhstanee n a fluid state, .and

to this end. I provide a steam pipe 10" sup ported o,n lugs 11"riirried by the brackets 11. which are suspended from the rover plate 11"". Said steam pipe 1z is conneeted, as shown in. to the inlet pipe 11- and outlet pipe 11.. The inlet and outlet pipes are stationarily arranged relatively .to the rotating support. and the steam pipen,

leads to the rotatable member a whieh is t'onnerteil with the inlet and outlet pipes by means of stufiing boxes 11" and 14 'respeetively. Thus, each of the thr'ee baskets of each section, as shown in the. present eniinto a trough 11" whieh carries a depending spout 11"", the latter traveliug-within the stationary trough 11" from wliieh the treating, suhstauee is returned to the point of supply i any suitable manner.

'l'he supports 1 1 and I, are mounted n the pedestals 1 eaeh sul'ipi'irt being provided with a gear su'rfare 1? with which ma as't etl'eet moveineut of the supports 11 and l; in the same dirertion,.frour the power sha'ft 1".

The materlal is fed. to the marhlne in anypresent embodiment, there are provided feeding tables 11 f. ha;v|ngf perforate bottoms a, formed of wire gauze or similar material, and side walls 11. 'l'he feedingtables" 11 are mounted mlueitieally disposed .ar-
